LOOKING FOR TAG & SHEET

I'm looking for the fender tag and build sheet for a 1968 Formula S Barracuda Vin # B299221. I have the original invoice. The car was sold by Langston Motors in Charleston Heights, SC to a sailor on the USS Daniel Webster. I believe I am the 4th owner. I've tracked the car to Florida and Tennessee. Like to know more about the car as I restore it.
